Embodiment 1

[0049] The present invention is described in detail below in conjunction with accompanying drawing;

[0050] in, figure 1 It is a schematic flow chart of the voice recognition-based video playback control method of the present invention, figure 2 It is a schematic diagram of performing voice and video in an embodiment of the present invention;

[0051] According to this embodiment, the voice recognition-based video playback control method includes:

[0052] S101: Train the voice of a certain user to extract voice features;

[0053] S102: Save the speech features of the above-mentioned specific user in a speech feature database;

[0054] S103: Receive a user's voice control command;

[0055] S014: Comparing the received voice control command of the user with the saved voice features of the user;

[0056] S015: When the voice feature of the user matches the voice feature of the user in the server, extract the voice control command and control video playback based on the vo...

Embodiment 2

[0064] The present invention is further described, wherein, the present application mainly includes: a speech feature training step, a speech feature recognition step, and a video control step. The above three steps of the present invention are described in detail below.

[0065] image 3 It is a schematic diagram of performing speech training in an embodiment of the present invention;

[0066] Such as image 3 As shown, the method mainly includes the following steps:

[0067] When a specific registered user opens the webpage, a speech recognition FLASH will be displayed in the webpage. This FLASH technology is relatively well known in the prior art, and will not be described in detail here.

[0068] Among them, when the system acquires that the user has not performed voice feature training, it will prompt the user to perform voice training, otherwise directly enter the next step;

[0069] Among them, the system will give some basic words, such as: start, pause, play, incre...

Embodiment 3

[0080] Wherein, the speech recognition step includes:

[0081] Receive the voice input by the user;

[0082] Carry out similarity measurement between the voice control command input by the user and the voice features of each instruction stored in the voice feature database;

[0083] According to the similarity between the two, it is judged whether the user's voice control command matches the features of the voice feature database.

[0084] In one embodiment, the user needs to click a specific voice operation button during viewing; Figure 4 It is a schematic flow chart of voice recognition video control according to an embodiment of the present invention;

[0085] Wherein, after the operation button is clicked, the voice control command is spoken within a specific time, for example, within 10 seconds, and the operation command spoken within these 10 seconds is considered valid, and is recognized and matched with the corresponding operation command , and react.

Abstract

The utility model discloses a video control method based on voice recognition. The method comprises the steps of training the voice of a user so as to extract voice features and storing the voice features in a voice feature library; receiving a voice control command of the user and comparing the voice control command of the user with the stored user voice features; when the user voice features are matched with the user voice features in a server, extracting the voice control command and controlling the video play based on the voice control command. After the technical scheme is adopted, the technical defect in the prior art that voice recognition is applied to a single machine or software for the features need to be downloaded is overcome; in addition, as the voice features of the application are stored in the voice feature library based on a specific person, the effect of recognizing based on the voice of the specific person can be realized; and moreover, the method is high in accuracy when being used for voice recognition and control. Furthermore, the invention also discloses a video control system based on voice recognition.

Description

technical field [0001] The invention relates to a video control method, in particular to a voice recognition-based video playback control method, which belongs to the field of voice recognition. Background technique [0002] At present, the task of computer speech recognition is to enable the computer to understand the sentences or commands spoken by humans and make corresponding actions. [0003] Among them, since the 1970s, computer speech recognition technology has made breakthrough progress in research. Now computer speech recognition technology is widely used in various fields, such as speech recognition dialing, voice search, voice control and so on. But there are some problems in existing computer speech recognition systems. Because computer speech recognition requires a lot of calculations, the existing computer speech recognition calculations are basically applied to stand-alone calculations, or need to download and install specific software to perform speech reco...
